This illustration, using figures from the most recent 2014 IPCC report, depicts that because only 800 gigatons of CO2 can be emitted by humanity before creating a 66 % probability that a 2 degree C warming limit will be exceeded and humans have by 2011 already emitted 530 gigatons of CO2, there are only 270 gigatons of CO2 that may be emitted after 2011 to limit warming to 2 degrees C. (For a more detailed explanation of these figures see, Pidcock 2013)

The steepness of these reductions curves is somewhat controversial because any calculation of a carbon budget which determines the steepness of the the needed reduction curve must make assumptions about when positive feedbacks in the climate system will be triggered by rising temperatures, yet these controversies are reflected in giving different probabilities about the likelihood of achieving a specific warming limit.

Though not specified in the Copenhagen Accord, this 2 °C warming limit is usually presumed to be relative to pre-industrial levels [19].

And so as a matter of international law under the Paris Agreement, national commitments to reduce ghg emissions must be based on achieving a warming limit as close as possible to 1.5 degrees C but no greater than 2 degrees C, a requirement often referred to as the level of «ambition» but national commitments also must be based on «equity» or «fairness.»

While there have been negotiations under way on the new agreement, there has also been an attempt to increase national commitments on greenhouse gas (ghg) emissions reductions in the short - term because mainstream science is telling nations that much greater reductions in emissions are necessary in the next few years to maintain any hope of keeping warming below 20 C, a warming limit that all nations have agreed should not be exceeded to give some hope of preventing catastrophic warming.

The actual amount of emissions reductions that are needed between now and 2020 is somewhat of a moving target depending on the level of uncertainty that society is willing to accept that a dangerous warming limit will be exceeded, the most recent increases in ghg emissions rates, and assumptions about when global ghg emissions peak before beginning rapid reduction rates.
